LUQENA M. MORDEN, OF WATERBURY, CONNECTICUT.

TEMPORARY BINDER.

To all whom it may concern:

Be it known that I, LUCENA M. MoRnEN, a citizen of the United States, of59 Grand street, Waterbury, county of New Haven, and State ofConnecticut, have invented certain new and useful Improvements inYrality of holes in the edges of perforated sheets, thereby holding themdetachably together for use in the binder.

The invention will be understood by reference to the annexed drawing, inwhich Figure 1 is a plan of the fixtures; Fig. 2 is an edge view of thesame; Fig. 3 is an end view of the same with the rings closed; and Fig.4 an end vew with the rings open.

The base a is shown of sheet-metal, with cam-shaft sockets b at one edgehaving a cam-shaft c journaled therein. The base has a longitudinalflange d along the opposite edge, and ears e are cut from notches e inthe base andbent upwardly in pairs, and the ringsections f and g areattached together upon a pivot h and are complemental to one another soas to form a complete ring when closed.

The section 9 is held stationary by having its shank rest upon the baseand upon the flange d, and it is held stationary by lugs t' bentinwardly from the tops of the ears .e. The section f is movable, and itsshank adjacent to the pivot it lies over the cam-shaft c, and a cam c isformed upon the shaft adjacent to each of such sections and proportionedto press such sections against the stationary sections g, and hold themovable sections locked, as in Fig. 3.

A spring It is provided to press each of the movable pivot-sections fnormally apart from the stationary sections, so that when the cams areturned outwardly as shown in Fig. 4, the sections are automaticallyopened to remove or change the perforated sheets. Such wire spring isconveniently supported at the side of the movable section upon one ofthe ears e by means of bent teeth Z punched from the ear and overlappedupon the body of the wire.

By the construction described, the pivot-bearings for the ring-sectionsand the socket-bearings for the camshaft are all formed integral withthe base, and are readily cut and stamped therefrom by suitable tools.The cam-shaft and the cams are readily made integral Specification ofLetters Patent. Application filed June 1.1906. semi No. 319.679.

Patented Nov. 12, 1907.

by bending cranks or offsets upon the shaft as shown in Fig. 2, the endof the shaft being bent transversely, or looped to form a handle forturning the same. The handle is so related to the cams that it lies uponthe base out of the way, as shown in Fig 1, when the ringsections areclosed.

In manufacturing the base, it is formed with projections b indicated bydotted lines in Fig. 1, which may be readily bent over the journals ofthe cam-shaft, as shown in full lines in Figs. 1 and 4, at theinterspaces between the cranks or cams c. The base a is shown narrowerthan the diameter of the rings, so that the fixed sections g projectover the flange d, which is notched to fit the under side of the ringand hold it laterally. It will also be observed that the transversearrangement of the ring-sections upon the base enables the cam-shaft tobe extended along the edge of the base, and that the cams operate tolock the movable sections f when they are rocked toward the sections g,as shown in Fig. 3.

The construction is very cheap to manufacture, and operates very quicklyand conveniently in opening and closing the ring-sections.

Having thus set forth the nature of the invention what is claimed hereinis:

' 1. In a temporary binder, the combination, with a longitudinallyextending base, of complemental ring-sections supported transverselyupon the base, one section of each ring secured immovably upon the baseand projecting over one edge of the same, and the other section of eachring being pivoted upon the base to rock transversely, a camshaftextended along the edge of the base beneath such movable ringsections,cams upon the shaft operating to close and lock such movable sections,and a spring arranged and operated to open the movable sections when thecam is turned to release the same.

2. In a temporary hinder, the combination, with a base having cam-shaftsockets along one edge and a series of pivot-bearings projected upwardtherefrom, of a series of ring-sections pivoted movahly upon the saidbearings, a shaft journaled in the sockets and having a cam to move eachof such pivot sections, and complemental ring-sections united to thepivot and held immovably upon the base, forming a series of closed ringswith the pivotsections when the cam is operated.

3. In a temporary binder, the combination, with a sheetmetal base havinga series of integral transverse ears bent upward from the base to formpivot-bearings and having locking lugs thereon, of ring-sections pivotedmovably upon the ears, compiemental ring-sections held stationary uponthe base by engagement with the pivots and with the locking lugs, andmeans for moving the pivot-sections to and from the stationary sections.

4. In a temporary binder, the combination, with a sheetmetal base havinga series of integral transverse ears bent upward from the base to formpivot hearings and having locking lugs thereon, of ring-sections pivotedmovably upon the ears, complemental ring-sections held stationary uponthe base by engagement with the pivots and locking lugs, wire springssecured upon the upturned ears and operating to hold the pivot-sectionsnormally open and means for moving the pivot-sections toward thestationary sections.

5. In a temporary binder, the combination, with a sheet metal basehaving cam-shaft sockets along one edge, and an upturned flange at theopposite edge, with a series of ears bent upwardly from the base to formpivot-bearings, of a series of ring-sections pivoted movably upon thesaid "10 bearings, a shaft journalecl in the sockets and having a thepresence of two subscribing witnesses.
